Animated boiling star. It can be the sun, or any star you like. It is very easy to change the color if you want it to be more white, blue etc etc.
The model slowly rotates itself and the moving gas around it rotates separately. Everything is included, model, scene, background, basically you load the scene, hit 'render' and receive the result as shown on the preview images.
The geometry consist of quad polygons only. The model uses subdivision surfaces and you can subdivide it on a higher level for close shots or keep it low poly for distance shots.
The background is a simple photo, you can easily replace it.
Please check out the video preview file, you can find it on the right of this description.
Note: NON-Lightwave users, as far as I know there is no way to convert this scene to other software since it uses application specific features.
